The measurement of body temperature is an important aspect of assessment prior to invasive procedures. The purpose of the study was to determine the level of agreement between temporal artery, noncontact infrared, and disposable oral electronic thermometers to a clinical reference device (nondisposable oral electronic thermometer) in outpatients prior to an endoscopic procedure. A descriptive, method-comparison study design was used to compare 3 noninvasive thermometers with a clinical reference device. Four noninvasive temperatures were measured with 3 test devices (temporal artery with ear tap; temporal artery without ear tap; disposable oral electronic; and noncontact infrared), followed by measurement with the clinical reference device (nondisposable, oral electronic). Differences (bias) and limits of agreement (±1.96 SD) were calculated for the test devices and graphed using Bland–Altman method. Clinically acceptable levels of agreement were set at a bias of 0.54 °F or less and precision of 0.90 °F or less. A total of 25 endoscopy patients (N = 14 female; N = 11 male) were studied, with temperatures ranging from 97.5 to 98.9, averaging 98.1 ± 0.3 °F. All thermometers, with the exception of the noncontact infrared (0.66 °F), had acceptable ranges for use in clinical practices. Findings from this study support the use of both temporal artery and disposable oral electronic thermometers in afebrile outpatients but not the noncontact infrared thermometer.
